The anion (negatively charged ion) Cl is the anion (chloride ion). It is generated when the element chlorine (a halogen) gets an electron or when a molecule such as hydrogen chloride is dissolved in water or other polar solvents. Chloride compounds like sodium chloride are frequently extremely soluble in water. [4] It is an electrolyte […]
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all
In biology, an organism is any organic, living system that functions as an individual entity. All organisms are composed of cells (cell theory). Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea. All types of organisms are capable of reproduction, growth
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and molecule is often used when referring to polyatomic ions.
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth‘s hydrosphere and the fluids of all known living organisms. “Water” is the name of the liquid state of H2O at standard conditions for temperature and pressure. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula H2O, indicates that
Frank Lloyd Wright (June 8, 1867 – April 9, 1959) was an American architect, designer, writer, and educator. He designed more than 1,000 structures over a creative period of 70 years. Wright believed in designing in harmony with humanity and the environment, a philosophy he called organic architecture. This philosophy was exemplified in Fallingwater (1935), which has been called “the best all-time work

Sanitation refers to public health conditions related to clean drinking water and ‘treatment and disposal of human excreta and sewage.’ Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially
